Mathematics related to real life
“There is a tank of water with two valves, one valve fills the tank, the other drains, how long does it take to fill the tank?” Our math books are full of these nonsensical questions. The question is questionable: “Is there a relationship between mathematics and real-life experiences?” Any intelligent person will get rid of the problem by closing the bottom tap! I am going to give an example of how I learned the concept of volume in my school. It was mandatory that we do constructive work for three hours every day. This was part of our education. This was part of Gandhi’s “Bread of Work” philosophy that worked to grow his own food. It was also part of Vinoba Bhave’s vision to acquire various skills by doing a socially productive work. For this I had to go to work in the stable for a few days. A new barn was then under construction. My teacher gave me the task of solving a specific practical problem. “Find the amount of water a cow drinks in a day How much water will be needed for all the cows in the stable? Then build a water tank that will quench the thirst of all cows. To build such a tank? Then acquire this number of bricks. “For more than a week I have addressed this mathematical problem. There were many tanks of different sizes. How to measure the volume? What was the relationship between the volume and the outer surface of a tank? In fact, I’ve built a water tank and, in the process, I’ve learned a lot from math in real life.
Learning through the kitchen
Another example of learning good science through participation in a useful social work. At our school, students had to prepare for cooking. Every day a hundred people were eating in the upheaval of the school. The responsibility for the kitchen has been entrusted to a group of eight people. Per capita expenditure per month was announced in advance. The food should be tasty, nutritious and expenses to be within the stipulated budget. The balance of these disparate acts was indeed a very difficult task! The potatoes were cheaper but it contained mostly starch and had to be thrown on the nutritional bases. Using the minimum amount of oil under the Indian Council of Medical Research (ICMR), we would have exhausted our entire budget in oil itself! None of us has had the experience of a good housewife. So it would be very difficult between the value of food and the monetary value to try to find a good balance. Many times our diet and our menu turned out to be totally useless. It simply was not possible to cook. We often misjudge the time it would take to cook lentils. So during the night, washing the dishes a mountain, we felt like wounded soldiers! The next day he looked directly at the face.
However, in the cooking process for the community, we have learned three very important lessons. These are elements of a nutritious and balanced diet, economy and cooking art. I still remember that the coriander green leaves were 6,600 units of vitamin A. In a few days, I learned many valuable lessons in community cooking. Unfortunately, I did not learn such valuable lessons during the decade I spent in medical school.
